At the Ente Keralam Expo 2025 in Kerala’s Alappuzha, a young electronics and communication engineering graduate from Kerala showcased a voice-powered device he invented, one that writes what you speak, just like a human scribe.

Ajay H, who shared the innovation on LinkedIn, introduced the project called Talk to Write, an AI-driven voice-to-pen system that turns spoken words into neat handwritten notes on paper using a CNC pen plotter. Powered by Raspberry Pi, Arduino (GRBL), and Python, the device was built with a strong focus on accessibility, particularly for individuals with disabilities.

“This platform allowed us to present how accessible, inclusive tech can be built by combining AI, embedded systems, and a clear vision for social impact,” Ajay wrote in his post.

In a video attached to the post, Ajay demonstrates the system by speaking into a microphone. The words “Department of Electronics” are then carefully written out on an A4 sheet by the machine, one letter at a time.

Ajay made sure to spotlight his team: Aparna Hari, Roobak Hari Nair, and Akash G Nair, praising their innovation and teamwork, calling them the “incredible team” behind the project.

The LinkedIn post, originally shared a few months ago, has now gone viral. Viewers from all walks of life have reacted with admiration and emotion. One person commented, “I can see the true potential of this project in real life. A blessing for disabled individuals.” Another noted how the device could be a huge help for students, saying it would “make writing assignments or records easy.”

A LinkedIn user said, “Every engineer thinks of this project idea while writing assignments, finally someone made it.”

One user recalled a heartbreaking scene from a movie where a disabled girl was left unable to write her exam because her scribe didn’t show up, a moment that ended in tragedy. They wrote, “Seeing your project gives me hope that we’re moving towards a world where empathy, accessibility, and support are no longer optional, but essential. Keep going, this matters.”
